Cum, :1 j.citizen of the United States, residing at- 5 South Ileiid. in the county of St. Joseph and State of Indiana. have invented certain new and useful Improvements in Emergency-Tires, of which the ft'illowing is a specification.

i\[y invention relates to emergency tires for automobile iind other vehicle wheels,

One object of the present invention is to provide a vehicle tire which is constructed in sections. and which may he handily stoi'ed away under the seat of an automobile. or other suitable place, so as to occupy t the least )ossible amount of space. l A further object of the invention resides l i t2 purpose. of preventing the lateral displacement of the tire.

The tire consists preferably of four see- '1 he base members are coneaved in cross-secdisposed grooves 18 formed in their sides corresponding to the length and curvature of the members. Each base member has oplieyond the side faces thereof, and a nari'owed lower portion 20, of a width adapted to snugly fit. between the clencher flanges in the provision of an automobile tire, which X in ayla rasil v and quit-lily assembled upon the rim of a wheel. as a substitute for a damaged or otherwise iiuscrviccable tire.

, .\nothci"objcct of the invention resides in j the provision of a sectional tire which may i laasst-tabled upon a clcnchcr rim, and the adjoining ends of two sections drawn together so as to give the tire as a whole a firm hiinliiig enga ement with the wheel iiiui.

i l i .\nother tllljttl of the invention resides in i the provision of a sectional tire. each section of which embodies means for attachment to the adjoining sections, ainl when assembled between the. flanges of a clei'ieher rim no other securing means will be iieces- '1 I Hlll'v- With these and other objects in view, the

a of construction as hereinafter described and pointed out in the claims.

In the drawings employed for illustrating the embodiment of the invention: Figure 1 is a'side elevation of a clencher wheel showing the tire. mounted thereon.

'lh e rubber tread member is folded over the sides of the base, aml inwardly extendl} mg ribs .22 formed along the side. edges l clamped against displacement by segmental dates 23 which overlap the edges thereof. The plates 23 are shown secured to the base by rivets .24. but. it is obvious that bolts aml i nuts may as well be. used for the purpose. so that. the same may be readily removed at 1 1 will and the rubber tread detached for thc i purposes of repair or replacement.

In practice the ribs are sons-what longer than the depth of the grooves so that, when the plates 23 are tightly drawn against the sides of the base, the ribs will be firmly com- )ressed into the rooves and the tread incin- )er securely loc (ed in position. in order to prevent the ends of the wooden bases from being exposed to and absorb wait" at. the section joints, and als to provide a cushion between the joints which will yield and form a tight, compact, anti-rattling joint, the tread member on each section has comparatively thin extensions 25, conforming to the cross-sectional formation of the base, and which are secured to the ends thereof in any suitable manner.

The segmental plates 23 have a treble function, viz,to lock the tread member to 3 the base, as above described; to connect the ends of the adjoining tire seetioiis to each tions 12. 13, H and 15, the base members 16- of which are preferably of wood having a I tough fiber, for the purpose of obtaining both strength and lightness of construction.

tioii, as indicated at 17, and have oppositely iositely disposed side portions 19, extending l1 ing seated in the concaved part of the base I other when mounted u 5 and to add strength to t ie structure of each section. The plates extend beyond one end of each of the sections 12, 14 and 15, as iiidicated at 26 in Fig. 5, and both plates ll terminate with the opposite ends of each of the sections 13, 14 and 15, as indicated at 27, the ends being sunken into the sides of the base for a short distance, so that the exteiisions 26 of the plates on the adjoining section wil loverlap and come tlush there with. The sections when being mounted upon the wheel rim are detachably locked together by passing threaded bolts 28, .29 and 30, through coinciding bolt holes in the plates and base, and applying a nut-to the op iosite ends.

n order to firmly bind the tire as a whole to the rim, and to prevent circumferential movement of the tire independent of the wheel, the sections 12 and 13, at their adjoining ends, have one plate on each section pen the wheel rim,

and on opposite sides extending beyond thcl base to form a waterproof and anti-rattling ends, as plainly shown in Fig. It, so that the: plate on one section o erlaps the plate which terminates with the end of the adjoiningsection and vice versa. have elongated apertures, as at 31, and the base members with ta )tlttl apertures, as ishown by dotted lines in Fig. t, the. elonlgaled apertures fully registering with each lothcr when the ends of the sections 12 aml i 13 are drawn together, but ordinarily they- F would but partially register with each other, las shown in l 'ig. =1. A partial registration of the a iei'tures would permit the small end of the w ll 32 to he messed therethrough,

and by forcing same tirough to the extent of its leugthfthc tapered portion of the shank 33, will draw the plates in opposite directions, and thus cause the tire as a whole, the remaining sections of which have previously been connected together, into tight frictional contact with the periphery ol the wheel rim. 'lhe wedge. bolt 32 has its shank llattened so that it will pass through the elongated openings and at the same time prevent turning of the bolt as the same is drawn through the apertures by the turning of a nut 34, applied to the end thereof. The wedge bolts are applied from opposite sides so as to secure uniformity of silt on the plates on both sides of the tire. the reference 3.) in Fig. (1,indicatcs metallic tubes embedded in the wooden base, the bore of which registers with the aperture of the adjoining plates, so that the ends of the wedge bolts will be, pro .icrly directed so as to meet the aperture in the p ates as the bolts are forced through from the opposite side.

From the foregoing description it will be seen that the sectional tire may be easily and quickly applied to a wheel in an emergentand when disassembled stored away Each of the plates' ,under the seat or other convenient part of 'an automobile in a compact manner. Its 5 "substitution for the regular clencher tire i which has become dellated by reason 0 puncture or other causes, perm ts the ma- Ieliine to be driven without inpiry to the iwheel rim and with practically the same cushioning etl'eetas the regular tire.

l-laving thus described my invention, what is clamed is 1. A sectional emergency tire for automobiles, each section comprising a base portion. a tread portion of resilient, waterproof material extending around the sides and; lover the ends of the base, and means for se- 1 curing the tread to the base and connecting the adjoining tire sections. 2. A sectional emergency tire for automobiles, each section com irising a base and a f itread member, inward y extending ribs on the tread member engaging corresponding grooves in the base sides, the end portions ol' the tread extending' ver the ends of the joint. with the adjoining sections. and means 1 for clamping the tread to the base and forming a locking connection with the adjoining sections.

3. A sectional emergency tire for antomobiles, each section comprising a base and a tread portion, locking plates adapted to clamp the side edges of the tread to the base and form a connection between the sections. the plates on two adjoining sections terminating flush with and extending beyond the. base ends in alternate relation, so as to overlap each other from opposite directions, and means assing through the overlapping plates [tilt sections from Opposite sides to draw the sections together in a uniform manner.

In testimony whereof I allix my signature, in presence of two witnesses.
